The disposable MICROLET®NEXT Lancet is used for capillary blood collection.

The disposable MICROLET®NEXT Lancet is used for capillary blood collection. The device comprises of a stainless needle encapsulated with a plastic and protective cap; the protective cap is twisted off to expose the needle for use. The device is sterilized by radiation. The needle body and protective cap form a sterile barrier to maintain the needle sterile.

The provided text describes a 510(k) premarket notification for a medical device, the MICROLET®NEXT Lancet, which is used for capillary blood collection. It is a Class II device. The document mostly focuses on demonstrating substantial equivalence to a predicate device (STERILANCE DISPOSABLE BLOOD LANCET, K221507) and regulatory compliance.

However, the provided text does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria for an AI/Software as a Medical Device (SaMD).

The document discusses non-clinical and clinical tests, but these are related to the physical performance of a lancet (biocompatibility, usability, shelf life, and the ability to obtain adequate blood volume for a blood glucose monitor), not the performance of an AI or software algorithm.

Therefore, I cannot extract the following information that would be relevant to an AI/SaMD study:

1. A table of acceptance criteria and the reported device performance (for an AI/SaMD): Not present, as this is not an AI/SaMD.
2. Sample sizes used for the test set and the data provenance: A clinical study "enrolled 131 lay persons with diabetes" and "120 completed the study." This is a sample size for a human-use study of a physical device, not an AI test set. Data provenance is not specified beyond "a single clinical site."
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for a lancet isn't established by experts in the same way it is for an AI interpreting medical images. The "ground truth" here is whether the lancet can obtain a sufficient blood sample for a BGMS.
4. Adjudication method: Not applicable.
5. Multi-Reader Multi-Case (MRMC) comparative effectiveness study: Not applicable. This is for evaluating human performance with and without AI assistance.
6. Standalone (i.e., algorithm only without human-in-the-loop performance) study: Not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Ground truth for the lancet's performance is the ability to obtain "adequate blood volume from fingertip and palm lancing to obtain a numerical result on the BGMS."
8. The sample size for the training set: Not applicable, as this is not an AI.
9. How the ground truth for the training set was established: Not applicable.

In summary, the provided document is for a physical medical device (a lancet) and not an AI/SaMD. Therefore, the specific details regarding acceptance criteria, test set, ground truth, and study design relevant to an AI/SaMD are not present.
